In the gripping episode Menace in Wax from the classic radio series Suspense, two English reporters, Roger and his colleague, find themselves embroiled in a dangerous investigation at Madame Tussaud's wax museum during World War II. The story unfolds on a stormy night in March 1941, as London faces the constant threat of bombings. Roger, eager to uncover a potential sabotage plot, arrives at the museum, where he is met by a night watchman who hints at strange occurrences within the eerie halls filled with lifelike figures. The watchman, Pearson, shares unsettling tales about the museum's past, including a chilling incident involving a guillotine that once belonged to the infamous executioner Sanson. This sets a foreboding tone as Roger begins to suspect that the museum may be more than just a tourist attraction.
